4. Constructed of materials and furnishings with low absorptive and non-porous characteristics.
5. Does not allow persons under the age of 18 to enter.
6. Contains prominently-displayed smoking cessation and health education signage and does not contain entertainment amenities.
7. When cleaned, cleaning staff are provided with P100 respirator masks.
8. If the smoking area is repurposed, all materials within the space must be discarded.

During performance verification, one of the sampling points for Feature 01 will be 2–5 m [6.6–16.4 ft] meters from the door to the smoking room and the door will be opened at least once every ten minutes during the testing period.
